How to Customize the BeagleBone’s Desktop Appearance
You use the Preferences tab of the Applications menu to set up the BeagleBone desktop environment in a way that’s comfortable, good-looking, and easy to use. To customize your desktop, choose Applications→Preferences→ Openbox Configuration Manager. After a second or two, you see the Openbox Configuration Manager, which includes many customization options.
With the configuration manager, you can change pretty much every single thing about the appearance of your desktop. Using the Theme tab, you can change the theme to one of the many predefined themes or installing themes that you fetch from the Internet. With the Appearance tab, you can change the font of all text that appears in your windows, such as the title, menu headers, and menu items.
You can also customize your windows, mouse, and the margins of the desktop. With the Desktops tab, you can change the names of your desktops to something that makes more sense.
These examples just scratch the surface of the customization you can do. Play around with the settings on the different tabs until you get the style that you prefer. Don’t worry — it’s impossible to break anything by merely changing its appearance.
